Washington State
Washington State is the number one apple producer in the United States, providing 70% of the nation’s apples.
The current climate in Washington is favorable for apple production; however, as temperatures rise it also
becomes more suitable for many apple pests. The codling moth (Cydia pomonella)’s suitable habitat is likely to
expand its range in Washington with rising temperatures, placing more orchards at risk of infestation. The United
States Department of Agriculture (USDA) Agricultural Research Service (ARS) has shown interest in codling moth
distribution because the moth has a well-defined temperature range for development, between 10° C to 31° C.
An analysis comparing satellite derived land surface temperatures (LST) and air temperatures measured from 36
weather stations revealed that LST is a suitable alternative to calculate growing degree days (GDD). Using Aqua
Moderate Resolution Imaging Spectroradiometer (MODIS) LST from 2003 to 2013, GDD for insect development
were calculated for the codling moth to show current at-risk areas. Furthermore, inclusion of the Coupled Model
Intercomparison Project phase 5 (CMIP5) multi-model ensemble forecasted climate changes for 2045 and 2065
were used to determine future pest ranges. Final products show that rising temperatures will allow codling moth
ranges to move closer to the Cascade mountain range and increase around the Columbia river valley.
Additionally, a rise in temperature will allow more growth time for the moth each growing season, ultimately
leading to larger pest populations. The current and long-range forecast risk maps benefit orchard managers by
improving pest management and better handling of current orchards.

MODIS LST are a good proxy measurement for
calculating GDD
Greatest risk areas from 2003-2013 for generational
growth of the codling moth are located east of the
Cascades
Climate projections suggest a northward extension of
the codling moth’s distribution
Future work should include precipitation in the analysis
to determine influence on insect development

different stations within the
top three apple producing
counties in Washington
state were included in this
portion of the analysis.
